spring increased. In practice, the springs are made strong enough to force the grip-- ping-blocks against the hubs with suilicient power to ret-ain the movable hinge members and with them the swinging` arms or shield members to which they are attached, in any position in which they may lbe placed. Should a positive lock be required, the screws are turned inward far enough to set the springs and to force the blocks posh tively into engagement with the hubs.

ln` the form illustrated in Fig. 6, the box which iucloses the hub consists of spring arms 29 having heads 30 through which the screw 3l passes. One of the heads is provided with a. socket 32 which receives the cup and a spring 28 bearing against the bases of the socket and the cup respectively. rlCheother arm is provided with a socket which receives a nut 33 which is engaged by a screw 31 passing through both heads. The spi-ing in this form aets to clamp the inner walls of the heads against the hub in 'the same manner that t e Ori eine blocks engage it in `the other form. i

The swinging arms are tubesv and the corresponding hinge members are provided withhubs 34 which tightly engage the ends of the tubes, as clearly shown in Figs. 2 and 7. lll/'here one member of a shield is a'ttached to a lillerein board, head 21 of the lower hinge has formed integral therewith av clip 35 which is bolted directly to the liller-in board, indicatedby 36 (see Fig. 7). Where a two member shield is used, it should be attached to the illenin board in some way that will permit the lower member to be'changed from the vertical to the zigzag position or vice versa. For this purpose l preferably use the wind shield clamp described and claimed 'in `my Patent Number 1,015,386, dated January 23, i912, and whicl'i, in 'the present instance, ll have in" dicated by ln order that the shield members may be retained in engagement, that is, so vthat-there may be no open joint between the shield members in either the zigzag or ordinary position, l, provide screw hol s indicated. by 38 and 39 in the frame of the lower shield member and attach the lower hinge to the lower shield member by means of the arm 2:2 which extends :from one member of the hinge and covers 'the holes. This arm is secured to the frame of the lower shield member by screws il which pass either through holes 38 or 39 and gage a block 42 lying within the frame. 'W hen the members Iare to be locked in the ordinary or vertical position, screws ll are passed through holes 38 and the inner ends v bf the frames of the upper and lower shield members will lie close together. ln order to provide tor the inclined or zigzag position of the lower membeml as in Fig. 8, l bevel the ends oi" the frame of the lower member, as at 43. In changing from the ordinary to' the zigzag position, screws @El are removed from holes 38 and are passed through holes 89. rIne lower ends oi the frame of the upper member in the adjusted position will lie in engagement with the bevels, as clearly shown in Fig. 8, and an open joint between the shield members will be avoided.

Having thus described my invention, l`

claim:

l. A hinge of the character described comprising a hub, a boX adapted to turn on 'the hub, and provided with a' transverse hole, gripping blocks in the holejwhich engage the hub, a screw passing freely through one block and having threaded e'n 'agement with the other', a spring bearinguigainst the screw and the Unthreaded blockrand an independently adjustable locking stop nut on the screw, i'or the purpose set forth.

Ei. hinge of the character described Voomprising a hub, a box adapted to turn on the hub and provided with a transverse hole, gripping blocks in said hole bearing on the hub, a screw provided with a shoulder and passing 'freely through one block and gaging the other, a cup bearing against the shoulder, a spring soclteted in the cup and bearing against the unthreaded block and an adjustable locking'stop nut on the screw.
